The present invention relates to guards for roofing gutters andparticularly to such removable guards cut in suitable lengths in theform of a screen either of perforated metal or wirecloth and designedtoprevent the entry of'foreign matter whichhas-a tendency to clog thegutter.

- Itis an object of the invention tQi provide such a gutter'guardorscreen which maybe readily'installed and easily removed by thehouseholder without the assistance of skilled help.

It is another object ofthe' invention to provide such a; guardor screenin a partlyfabricate'd' form which is readily cut and formed into itsfinal'form' by the householder and may, therefore, be lower in its saleprice.

Other objects and features of' the invention will appear when thefollowing description is considered in connection; with the annexeddrawings Figure" 1' is a broken plan view of a section of gutter guardor screen in accordance with the preferred form of my invention;

Figure 2 is a cross-sectional'view of the screen of Figure 1;

Figure 3- is a detailed view showing the alteration ofthe cross-sectionof the screen wire in order to make it readily bendable at selectedpoints;

Figure 4- shows a cross-section of one. form of roofinggutter and theadjacent building wall together with a guard'in accordance with Figures1 and 2 in placeto preventthe entering or foreign matter intothe gutter;

Figure 5 is a view similar to Figure 4' but showing a second form of myinvention in cross sec tion and in position on theroofi'ng gutter;

Figure 6 is a plan view of the form; of screen shown in section inFigure 5;

Figure 7 is a sectional view showing the screen of Figure 6;

Figure 8 is a view similar to Figure 4 showing a third form of thescreen of my invention in place on a roofing gutter;

Figure 9 is a plan view of the screen of Figure 8; and

Figure 10 is a cross-sectional view of the screen of Figure 9.

Referring now to the drawings and particularly to Figures 1' and 2thereof, the screen of this form of my" invention comprises the screenproper I o which is provided with the selvage edge it. This screen is,in its preferred form, made incontinuous lengths andmay be composed, forexample, of wirecloth of three mesh to the inch and approximately eightinches wide. The wire 3 Claims; (01. 108-40) diameter used may be thatcommonly used co1 nmerciall-y and; known as hardware galvanizedwirecloth.

Approximately one inch from one edge of the wire In the strands runningin the direction per-' pendicular tothe edge are scored or weakenedso'that the screen may be readily bent along this line. This scoring orweakening is indicated at; l2 in Figure 1 Likewiseat approximately twoinches from the edge and parallel to the edge the strands are weakenedby similar score lines l3. These points of weakening or scoring may beprocured in any one of a number of manners. Thus the wiremay bemechanicallyflattened' at points such as I 2 and I3 to provide thelineof bending and the flattening may be in either of the forms shown inFigure 3, that is, maybe either rectangular in section as indicated at Win Figure 3, or a relatively round oval as indi cated at l5 in Figure 3or may bea relatively flat oval as indicated at It in Figure 3. Ii.desirable, the lines of bending may be improved by omitting a strand ofwire parallel to the edge at" the sectionwhere the bending is totakeplace or instead of 'scoring'the wires asshown in Figure 1 acomparable result may be obtained by locally heating the transversewires in the areas such as l2 and I3 by means of high frequency currentsto-the' annealing point of the cold" worked steel (IOOO F. to 1-100 F2)and allowing the product to:cool in airthussoftening'the steel wires onthe bending: lines;

Due tothe' construction above described} the gutter guard or screen ofmy invention maybe shipped Itothe user in a roll, for example, of theconventional type of I00 feet in length and may then. be cut-in shorterlengths and'bent' to the form: shown in- Figure 2; that is; may be bentthrough-130 alongthe line formed by the weak'-- ened areas I 3 andthenbent'in-the opposite direc-- tion along the line; indicated' by'theweakened area I2: As a result the screen is provided with the=two bendsdesignated n and ['8 inandl l and; as-so bent isin condition to beapplied tothe roofing gutter in convenient sections."

The application to the gutter is extremely simple; as is indicated inFigure 4; in which the unbent selvage edge rest's; on the roof' 20} andthe portion- [9 extending downwardly from the bend I 8 bearsagai'ns'tthe gutter edge 2+ and holds the screen or guard in its proper positionby its own weight. It will; of course,-. be'undeifstood that the formofgutter shown in Figure 4' is merely illustrative and that the gutterguard of my invention is equally applicable to the many 3 other forms ofroofing gutters which are in common use and particularly togutters madeof wood.

In the third f orm oi my invention shown; in --I?-figures 8;-9 and 10,each edge of the screen sectio-n'is enclosed a metal member, the

If desirable the member 36 may be centerpunched as indica'tedat 38 to enhancethe-gripping action of the memberupon the screen or the same effect may be obtained by stapling. In -alike manner a metal member 30 preferably of zinc is attached at'theother edge of the guard or screen section, this member 30 being formedsimilarly to the member 36 and being provided at the end of its lowerextension with abend 33 which servesto stiffen the edge. Further, a'bend 3l-in members 30 and 36 serves to improve the contact of thewirecloth with the zinc strip and in the case of member 35, member 3lalso provides suificient overhang to prevent mentioned above-inconnection with the form of .11 extending along said wirecloth parallelto the -other edge and spaced therefrom, and a second line "oFWeaKnedareas in the transverse wire,
